Although many young people toil away in anonymity with hopes of living out their dreams one day, Soulja Boy Tell 'Em shared the stage with one of the biggest rappers on the planet as a teen.

"When I was 17, I flew out to Las Vegas to perform at the MTV VMAs with Kanye West," SB describes in this week's episode of "When I Was 17," also featuring Jay Sean and Tony Award-winning actress Kristin Chenoweth.

The "Pretty Boy Swag" star, 20, was a special invited guest of Kanye's during the 2007 Video Music Awards at the Palms. West was one of the few artists that night to perform in one of the themed suites instead of the house. SB, however, was restricted to a small room away from the action.

"We were up in this huge super-suite with alcohol, everything," he recalls. "There were girls, all of that. But, they were telling me, since I was 17, I couldn't go to certain areas of the suite. I had to stay locked off in one part of the suite until the show. So I stayed in this one little room. But it was fresh, though, because they laid it out: They had video games and snacks.

"Mind you, [I was] 17 and from the 'hood, ain't never had nothing," SB added. "I'm in Las Vegas for the first time, so it was mind-blowing. I was doing all these things. We had a food fight. We were tearing the suite up!"

"When I Was 17," -- this week featuring Soulja Boy Tell 'Em, Jay Sean and Tony Award-winning actress Kristin Chenoweth -- premieres Saturday at 11 a.m. on MTV.
